     •   Native HW acceleration for multi-streaming MPEG-2 (SD & HD) video encode/decode that enables
         simultaneous playback and record and picture in picture.

     •   Adaptive de-interlacing enables enhanced visual quality of interlaced content on progressive
         displays.

     •   Intel® Dual Frequency Graphics Technology support that allows the chipset to dynamically switch
         render clock frequency to match graphics workloads delivering enhanced power savings.

     •   4GB maximum memory support

     •   Support for Dual Channel DDR2 400/533/667-MHz Memory Technology with peak bandwidth up
         to 8.5GB/s, a 60% improvement in peak bandwidth over DDR533

     •   PCI Express Bus Architecture delivers a 4x increase in discrete graphics bandwidth and a 2x
         increase in I/O bandwidth

     •   Intel® High Definition Audio with increased bandwidth that enables 32-bit output and 192-kHz
         multi-channel audio. Multi-streaming capabilities enable support for separate audio channels with
         independent audio streams to different devices.

     •   Integrated high speed USB 2.0 enables up to 15x faster data transfer rate of USB 1.1 and backward
         compatibility to support for USB 1.1 devices. The Mobile Intel® 945 Express chipset family
         provides support for 8 USB 2.0 peripherals.

     •   Direct Media Interface (DMI) with up to 2-GB/sec concurrent bandwidth. DMI provides up to 4x
         faster I/O bandwidth compared to previous Intel proprietary Hub link I/O interface.

     •   Integrated low voltage differential signal (LVDS) interface that enables the notebook display panel
         to connect directly to the chipset and eliminates the need for a video controller hub component. The
         result is higher integration for savings in mother board space and reduced bill of materials cost for
         OEMs.

     •   Dual Independent Display allows viewing two independent video sources when an external monitor
         or panel is connected to the notebook.

     •   Intel® Stable Image Technology is a capability built into the chipset and enabled in the BIOS. This
         silicon technology provides greater IT software image stability by enabling simple chipset hardware
         changes without triggering the "new hardware found" message—eliminating automatic and
         unnecessary re-qualification.

     •   Serial ATA is a storage interface technology that provides up to 150-MB/Sec transfer rate for disk
         traffic and provides aggressive link power management functionality.

     •   Intel® Display Power Saving Technology 2.0 (Intel® DPST 2) reduces display backlight power by up
         to 400-mW with minimal visual impact to the end user (depending on Intel DPST settings and
         system use).

     •   DDR2 Memory self-refresh provides chipset and DIMM power savings by putting memory into a
         reduced power state when display is still active on DDR2 based platforms.

     •   Integrated TV Out functionality provides the ability to use a TV as an output device for movie
         playback, digital images, and gaming.

     •   DirectX* 9 integrated graphics solution for high definition playback and 3D games.

Scientific Experience: SPEC* CPU2000
SPECint_rate_base2000 and SPECfp_rate_base2000 are capacity-based metrics used to measure throughput of a
computer that is performing a number of tasks. This is achieved by running multiple copies of each benchmark
simultaneously with the number of copies set to the number of logical hardware cores seen by the operating system.

Wireless connectivity and some features may require you to purchase additional software, services or external hardware.
Availability of public wireless LAN access points limited and some hotspots may not support Linux-based Intel® Centrino®
mobile technology systems. System performance measured by MobileMark* 2005. System performance, battery life,
wireless performance and functionality will vary depending on your specific operating system, hardware and software
configurations. See http://www.intel.com/products/centrino/more_info for more information.

Performance is measured on pre-production systems and BIOS. Final benchmarks based on the final production system
and BIOS may vary from these results. Performance tests and ratings are measured using specific computer systems
and/or components and reflect the approximate performance of Intel products as measured by those tests. Any difference
in system hardware or software design or configuration may affect actual performance. Buyers should consult other
sources of information to evaluate the performance of systems or components they are considering purchasing. For more
information on performance tests and on the performance of Intel products, visit
http://www.intel.com/performance/resources/limits.htm.
